VLSI Symposium Eyes 65-nm Logic News & Analysis 5/31/2003 Post a comment Though 90-nanometer designs are not expected to move into early commercial production until late this year, about a dozen papers at the 2003 VLSI Technology Symposium will target 65-nm design rules.<
Low-Cost Techniques for Sound Generation News & Analysis 5/31/2003 Post a comment We'd all love to have a color display attached to the systems we design. It would make communicating with the user so much easier. But most of us don't have that option. By using sound, we can offer the user more information with only a small increase in system complexity. David Hinerman explores some of the hows and whys of installing sound output in a system.

Statistical Process Control Can Improve Automated Production Testing -- Part 2: Implementation News & Analysis 5/30/2003 Post a comment In Part 1 of this ChipCenter feature article, we looked back in time and traced events that led to the adoption of statistical process control in an example automated test-and-measurement application. However, the implementation of a robust SPC process for the purpose of guaranteeing performance requires the measurement of key test points with a repeatable working standard. In this Part
2 conclusion, we examine these requirements.

Consortium Vows to Simplify IP Reuse in SoCs News & Analysis 5/29/2003 Post a comment A group of EDA, silicon intellectual property (IP) and semiconductor vendors will announce the formation of a consortium at the 40th Design Automation Conference (DAC) that will work to facilitate the integration of IP blocks into SoC designs. The consortium is believed to be working on ways to define "metadata" that goes beyond simple I/O information for IP blocksb
Leakage Current Leads 90-nm Rogues' Gallery News & Analysis 5/29/2003 Post a comment As leakage current shoulders its way to center stage in chip designers' gallery of horrors, leading-edge design teams are rapidly developing ad hoc techniques to minimize its impact. And while the EDA industry is characteristically lagging the leading-edge need, at least one vendor is moving aggressively to catch up, formulating both a tool and a methodology for reducing a specific source of leakage current.
Chip vendors zero in on wireless Product News 5/29/2003 Post a comment Power-managing ICs in wireless products are now playing a major role in system-level solutions. Cell phones, which are being combined with PDAs and cameras, are becoming increasingly small, dense and power-hungry, offsetting the size and energy density advances made by the lithium-ion battery sources powering them.
Analyzing the Challenges Facing HSBI: Part 2 News & Analysis 5/29/2003 Post a comment The HSBI initiative has launched a 5- to 6.25-Gbit/s interface for communication backplane architectures. But for this initiative to be successful, developers must face some difficult backplane design decisions. Here's a look at those challenges.
Constant current regulation overcomes LED quality variations News & Analysis 5/28/2003 Post a comment White LEDs are displacing cold cathode ray tubes as the preferred backlight for small CRT displays. While the prices of white LEDs have dropped, there is still a great deal of manufacturing inconsistency. A dim LED on an array of four or six will create a noticeable dark spot on a small LCD screen. The solution, explains Maxim's cell phone apps manager, is a constant current topology-one that supports both serial and parallel LEDs.

Current, voltage and temperature govern Li-Ion battery charging News & Analysis 5/28/2003 Post a comment Portable applications have many unique battery requirements. They require a high-energy density to provide both transient and continuous power. They need to be lightweight with small footprints, and they need to be safe from potential abuse. But how do you charge these devices. From the May issue of Planet Analog magazine, a National Semiconductor applications engineer discusses charging circuits and scenarios for a variety of chemistries.

Expecting the unexpected News & Analysis 5/26/2003 Post a comment Unexpected shifts in demand, pricing, and production capacity are nothing new for Glyndwr Smith and Allan Cole, who each have about 35 years of experience in the passives business. Yet, turning points in market conditions haven't gotten easier for the industry veterans to predict.
Mobile computing sets pace for color displays News & Analysis 5/26/2003 Post a comment An emerging generation of advanced cell phones and PDAs is accelerating the deployment of high-performance color displays, enabling LCD suppliers to strengthen their dominance in the market for small panels and stiffen their competition with organic LED (OLED) suppliers.
Advances in System-Level Design Roll Out News & Analysis 5/23/2003 Post a comment The electronic system-level (ESL) software market will expand this week as Future Design Automation Corp. rolls out a C-language synthesis system and Summit Design Inc. adds hardware/software co-design to its graphical Visual Elite tool.
